  • Page 13: Introduction

    INTRODUCTION GENERAL DESCRIPTION The LP 33 Series Uninterruptible Power Supply (UPS) provides the energy supply for critical loads which need a reliable, continuous free from voltage disturbances and frequency fluctuations supply. In case the mains fails, or it exceeds the permitted tolerances, the energy to supply the load is furnished by the battery with a backup time dependent on its capacity, until the mains recovers.
  • Page 14: Description

    If chosen the ECO Mode, the SSM transfer the load from mains to inverter in case the utility fails. Back-Feed Protection All LP 33 Series UPS’s are equipped with an automatic system for the protection against voltage back feeding towards Utility, through the Bypass (Applied Standard IEC 62040-1).
  • Page 15: Operation Modes

    ECO Mode cannot be enabled for RPA Parallel System. Attention: A single unit equipped with a RPA - Parallel board, must be considered as parallel, thus disabling ECO Mode. Modifications reserved Page 15/103 OPM_LPS_33E_60K_M12_2GB_V010.doc Operating Manual LP 33 Series 60-80-100-120 kVA / S2...
  • Page 16 When enough inverters to supply the load have been restarted, the load will be transferred from the automatic bypass back to the inverter bus-bars. Modifications reserved Page 16/103 OPM_LPS_33E_60K_M12_2GB_V010.doc Operating Manual LP 33 Series 60-80-100-120 kVA / S2...

  • Page 18: Rpa Parallel System

    RPA PARALLEL SYSTEM The RPA (Redundant Parallel Architecture) allows to extend the unit to a Parallel System with 2, 3, or 4 units LP 33 Series connected on the same bus, which ensure the highest reliability rate and increase the power availability.
  • Page 19: Ups Paralleled On The Same Battery

    A Parallel System with a Common Battery for two or more UPS, requires a particular installation and adequate setting of some parameters, (accessible only through password), and can therefore only be done by a qualified GE engineer. Usually each UPS Unit runs with its own Battery.
